I2C Interface Test with FPGA IP and JTAG

Accelerate Testing. Eliminate Firmware Dependencies.

Why It Matters

This methodology empowers design and test teams to work in parallel, no more waiting on firmware. By decoupling functional testing from software readiness, you unlock faster prototyping, better diagnostics, and reusable test assets that scale across projects.

What You'll Learn in This eBook

Why wait for a board to boot or firmware to be ready before testing I2C interfaces? With just three assets, on-board IEEE 1149.1 JTAG, and embedded instrumentation IP, you can run at-speed functional tests on non-operational prototypes. That means faster development cycles, earlier validation, and smarter engineering workflows.

Structural Testing with JTAG/Boundary Scan

Catch assembly faults, like shorts and opens, before they slow you down.

Functional Testing Without Firmware

Validate I2C interfaces using embedded IP in an FPGA, no need for bootable boards or completed software.

Embedding IP into an FPGA

Learn how to temporarily insert and remove test IP, enabling reuse across designs and maximizing efficiency.

Real-World Example: I2C I/O Expander

See how this method applies in practice, including high-speed SPI Flash and EEPROM programming.
